Synthesis of Ditetrahydrofurfuryl Carbonate as a Fuel Additive Catalyzed by Aminopolycarboxylate Ionic Liquids
摘要:
A new series of aminopolycarboxylate ionic liquids were designed, synthesized, and applied for efficient and selective synthesis of ditetrahydrofurfuryl carbonate (DTC). Tetraethylammonium nitrilotriacetate ([N-2222](3)[NTA]) was demonstrated to show the best catalytic performance, in which DTC could be obtained at a yield of 80% under optimum conditions.
A diesel fuel and additive mixture is useful for reducing particulate matter emissions while improving or at least not aggravating oxidative stability during combustion. The additive includes at least one compound having a general formula selected from the group consisting of:
and combinations thereof, wherein: R is a saturated or unsaturated hydrocarbon having from about 1 to about 6 carbons. The additive is effective in diesel at concentrations as low as from about 50 to about 1000 ppm by weight.
